Mold for forming projection on extruded bar for combining LED bar, and the extruded bar

摘要

The present invention relates to an extruded bar having a preliminary projection to be formed into a dove tail engaging projection slidingly coupled to a key hole-type engaging groove of an LED bar. And a shaping portion formed with a projection, wherein the head of the preliminary projection is pressurized by the punch so that the head of the dove tail coupling protrusion is formed into a D shape so that the head of the dove tail coupling protrusion is formed into a D shape. A second mold having a first mold having a forming groove constituting a part thereof, and a rectangular protruding end partially inserted into a first entry portion recessed into a D-shape of the forming groove to form the remaining part of the forming portion. Joining projection molding die of extrusion bar for joining LED bar, characterized in that it is made of a metal mold and the LED dovetail coupling projection of the D-shaped head by the mold It provides for the extruded bar linkage.
